The eggNOG database is a database of biological information hosted by the EMBL.

It is based on the original idea of COGs (clusters of orthologous groups)[2][3] and expands that idea to non-supervised orthologous groups constructed from numerous organisms.

[4] The database was created in 2007[5] and updated to version 4.5 in 2015.

[1] eggNOG stands for evolutionary genealogy of genes: Non-supervised Orthologous Groups.
